All fields are always initialized, so we don't need to initialize them
by default. This lets us send types over IPC that can't be
default-constructed, such as a Variant without Empty.
At some point, we stopped ever constructing invalid messages. This makes
that clearer, and will allow us to stop requiring that IPC arguments be
default-constructible.
Remember the query, so that if you're filtering for "color" on the
computed style tab, and switch to the resolved style tab, it's filtered
for "color" too.
This means we also can save looking up the filter text when a new node
is inspected.
If you have a search filter and then click on a different node, this now
applies the filter to the new node's properties, instead of showing all
of them.
These were previously skipped on macOS, due to hard to
fix inconsistencies in the exact produced pixels.
Turns out, this is not just a macOS thing. The same sort
of hard-to-spot slight pixel deviations are present on
arm64 Linux as well.
Explicitly link final targets with OpenSSL to ensure that the vcpkg
version is loaded instead of the system one.
Before this change we would inherit `libcrypto.so` and `libssl.so` from
other dependencies, like Qt, that do not have their RPATH rewritten.
This would cause the loader to prefer the system libraries over the
vcpkg ones causing all sorts of version mismatch issues.
The effectiveness of this change can be verified with
`readelf -d ./bin/Ladybird` showing `libcrypto.so` and `libssl.so` as
direct dependencies, before they would not appear. Additionally, `ldd`
will show `libcrypto.so` and `libssl.so` pointing to the vcpkg builds.
When drawing a table, some of the CSS properties must be moved from the
table grid box to an anonamyous table wrapper box. One of these
properties is `position`. `z-index` however is not. This leads to the
following behavior if a table has both `position` and `z-index`:
* The wrapper box has the `position`, but a `z-index` of `auto`.
* The grid box has the `z-index`, but `position: static`.
This effectively means that the `z-index property is ignored since it
has no effect on non-positioned elements. This behavior contradicts what
other browsers do and causes layout issues on websites.
To align Ladybird behavior with other browser this commit also moves the
`z-index` property to the wrapper box.
If the regex always matches the input, even if it's past the end, then
we need to stop execution of the regex when it's past the end. This
corresponds to step 13.a and prevents it from infinitely looping.

The usage of color-scheme was introduced in commit:
ce5cd012b9
This reverts the Inspector to use self-selected colors, as the default
color-scheme colors do not look great in this window.
If the expansion of a custom property in variable expansion returns
tokens, then the custom property is not the initial guaranteed-invalid
value.
If it didn't return any tokens, then it is the initial
guaranteed-invalid value, and thus we should move on to the fallback
value.
Makes Shopify checkout show the background colours, borders, skeletons,
etc.
Our existing coalescing mechanism for input events didn't prevent
multiple mousemove/mousewheel events from being processed between paint
cycles. Since handling these events can trigger style & layout updates
solely for hit-testing purposes, we might end up doing work that won't
be observable by a user and could be avoided by shceduling input events
processing to happen right before painting the next frame.
Currently we create URLs such as 'about:blank' through the StringView
or ByteString constructor of URL. However, in order to elimate the
use of URL::is_valid, we need to get rid of these constructors as it
makes it way too easy to create an invalid URL.
It is very cumbersome to construct an 'about:blank' URL when using
URL::Parser::basic_parse. So instead of doing that, create some
helper functions which will create the 'about:XXX' URLs with the
correct properties set.
Conveniently, this is also a much faster way of creating these URLs
as it means we do not need to parse the URL and can set all of the
members up front.
The new test case crashes during bytecode generation due to
`emit_super_reference` not correctly generating the reference record
for the property access.
MediaQueryList will now remember if a state change occurred when
evaluating its match state. This memory can then be used by the document
later on when it's updating all queries, to ensure that we don't forget
to fire at least one change event.
This also required plumbing the system visibility state to initial
about:blank documents, since otherwise they would be stuck in "hidden"
state indefinitely and never evaluate their media queries.
Instead of checking all elements in a document for containment in
`:has()` invalidation set, we could narrow this down to ancestors and
ancestor siblings, like we already do for subject `:has()` invalidation.
This change brings great improvement on GitHub that has selectors with
non-subject `:has()` and sibling combinators (e.g., `.a:has(.b) ~ .c`)
which prior to this change meant style invalidation for whole document.
The Linux IPC uses SCM_RIGHTS to transfer fds to another process
(see TransportSocket::transfer, which calls LocalSocket::send_message).
File descriptors are handled separately from regular data.
On Windows handles are embedded in regular data. They are duplicated
in the sender process.
Socket handles need special code both on sender side (because they
require using WSADuplicateSocket instead of DuplicateHandle, see
TransportSocketWindows::duplicate_handles) and on receiver side
(because they require WSASocket, see FileWindows.cpp).
TransportSocketWindows::ReadResult::fds vector is always empty, it is
kept the same as Linux version to avoid OS #ifdefs in Connection.h/.cpp
and Web::HTML::MessagePort::read_from_transport. Separate handling of
fds permeates all IPC code, it doesn't make sense to #ifdef out all this
code on Windows. In other words, the Linux code is more generic -
it handles both regular data and fds. On Windows, we need only the
regular data portion of it, and we just use that.
Duplicating handles on Windows requires pid of target (receiver)
process (see TransportSocketWindows::m_peer_pid). This pid is received
during special TransportSocketWindows initialization, which is performed
only on Windows. It is handled in a separate PR #3179.
Note: ChatGPT and [stackoverflow](https://stackoverflow.com/questions/25429887/getting-pid-of-peer-socket-on-windows) suggest using GetExtendedTcpTable/GetTcpTable2
to get peer pid, but this doesn't work because [MIB_TCPROW2::dwOwningPid](https://learn.microsoft.com/en-us/windows/win32/api/tcpmib/ns-tcpmib-mib_tcprow2)
is "The PID of the process that issued a context bind for this TCP
connection.", so for both ends it will return the pid of the process
that called socketpair.

* Use SpecializationOf for Optional and Variant concepts
* Remove inline because it is implied by constexpr
* Reorder declarations from less to more specialized (in common sense)
